Abstract: A system comprising a well drilled into an underground formation comprising hydrocarbons; a water supply; a steam production facility, the steam production facility comprising a filter to remove at least 80% of a quantity of divalent cations in the water supply; an exchange resin to remove at least 80% of a quantity of divalent cations in a filtered water stream that has already passed through the filter; a steam injection facility connected to the well and the steam production facility, adapted to inject the steam into the well.

Abstract: A process for producing a pressurised CO2 stream in a power plant integrated with a CO2 capture unit, wherein the power plant comprises at least one gas turbine (1) coupled to a heat recovery steam generator unit (2) and the CO2 capture unit comprises an absorber (18) and a regenerator (21), the process comprising the steps of: (a) introducing hot exhaust gas exiting a gas turbine into a heat recovery steam generator unit to produce a first amount of steam and a flue gas stream (17) comprising CO2; (b) removing CO2 from the flue gas stream comprising CO2 by contacting the flue gas stream with absorbing liquid in an absorber (18) to obtain absorbing liquid enriched in CO2 (20) and a purified flue gas stream; (c) contacting the absorbing liquid enriched in CO2 with a stripping gas at elevated temperature in a regenerator (21) to obtain regenerated absorbing liquid and a gas stream enriched in CO2 (23); (d) pressurising the gas stream enriched in CO2 using a CO2 compressor (24) to obtain the pressurised CO2 stre

Abstract: The present invention provides a lubricating oil composition comprising at least one type of base oil selected from mineral oils and synthetic oils, and a succinate ester and a sarcosinic acid as rust prevention agents. The succinate ester content is preferably set at 0.01 to 0.1 wt. %, and the sarcosinic acid content is preferably set at 0.001 to 0.01 wt. %. Further, they are preferably set such that the resulting weight ratio of the succinate ester content and sarcosinic acid content is 1:0.01 to 0.7. The lubricating oil composition according to the present invention shows excellent rust prevention properties and a satisfactorily long oxidation lifetime. Further it allows to attain a high level of anti-sludge performance and extreme pressure performance and lubrication performance, even when it is used for example in turbine bearings in combined cycle generators having multiplier gears operated under severe high temperature and high pressure conditions.

Abstract: Process to optimize the yield of base oils from a Fischer-Tropsch derived feed by performing the following steps (a) performing a hydroconversion/hydroisomerisation step on part of the Fischer-Tropsch derived feed; (b) performing a hydro-conversion/hydroisomerisation step on another part of the Fischer-Tropsch feed at a conversion greater than the conversion in step (a); and (c) isolating by means of distillation a fraction boiling in the base oil range from the two reaction products obtained in steps (a) and (b) and performing a pour point reducing step on said fraction.

Abstract: Device for the separation of liquid droplets from a gas stream comprising a plurality of wave plates (1, 2 and 3) arranged close to one another in such a way that a passage (5, 12) is defined between two adjacent plates, which passage alternately comprises a narrowing part (21) and a widening part (22) that is joined to the narrowing part (22), wherein a bend in the passage lies between the largest width of the widening part (22) and the smallest width of a narrowing part (21) that is joined to the widening part (22).

Abstract: A novel process is disclosed for the preparation of cyano-substituted cyclopropane derivatives of the following general formula: ##STR1## wherein R.sub.1, R.sub.2 and Hal have the meanings given in the description. The process comprises the steps of cyclizing and dehydrohalogenating, in the presence of a base, a 4,6,6,6-tetrahalo-2-cyano-3,3-dialkylhexanoic acid or an alkyl ester thereof, followed by thermal decarboxylation of the resulting cyclized and dehydrohalogenated product. Under selected conditions cyclization, dehydrohalogenation and decarboxylation occur simultaneously in one reaction zone. The resulting cyano-substituted cyclopropane derivatives are useful as intermediates in the production of insecticidally active compounds.

Abstract: A method of discharging residues resulting from gasification of fuel in a chamber filled in a lower portion thereof with water and having a gas cushion at high pressure above the water level, in which the residues accumulating in the chamber are discharged through a sluicing container connected to the lower end of the chamber and conveyor means connected to the sluicing chamber.
